NGC主机互换大型机板TRIFORCE是任天堂、namco和世嘉3个好基友合作而成的街机机板。而这个机板和NGC也是亲兄弟,很多参数和NGC都一模一样。但有許多不同的地方,包括比GC大一倍的1T-SRAM容量、增設世嘉的GD-ROM及可升級的RAM模組等,也能让家用主机与大型电玩相互间的移植更具效更具效率.性能方面在软件展示中已经获得了专业人士的认可,

Notes : Conceived as a joint venture between Sega, Namco and Nintendo to produce a low cost arcade system, with even talk of multiplayer games between people in arcades and home consoles using the GAMEFORCE network. 8 e$ s! [8 t: g3 A* X- W
Origonally thought to be just an arcade/jamma compatible system, this is now know to be around twice as powerfull as the home variant, : K) p1 Z+ t8 D8 H' W* ^* _
The only details being leaked that it has 48 MB of 1T-SRAM in place of the standard "cube's" 24, so to this end I have taken out all of the specs for the system an just replaced it with what we know about it so far.

Hardware Notes : Sega have made the Naomi GD-ROM drive compatible with the triforce as well, it is unknown if this will be used by Namco and other manufacturers as well.
